[122.11] A New Variable O Star in Cep OB 1

J.A. Davis, K. DeGioia-Eastwood (NAU)

We report a new variable O star in Cep OB 1. First cataloged
as LF 4 +55 471 by McCuskey (1955, ApJS 2, 75), the star was
classified at the time as an O5 using an objective prism.
Since that time, this 11th magnitude star has gone basically
unobserved except for making it into several more catalogs.
We have been observing this star photometrically at the
Lowell Observatory 31-inch telescope using the National
Undergraduate Research Observatory camera. The star is
clearly variable, although with more than 300 data points we
have yet to determine the type of variability. The authors

Northern Arizona University through AST-0453611.
